Answer:
48 burpees & 80 squats
Step-by-step explanation:
Let burpees= x
Let squat = y
For every 12 burpees Melinda did, she did 20 squats.
X/y =12/20
20x= 12y
X= 0.6y
Melinda did a total of 128 squats and burpees
X+y= 128
But x= 0.6y
0.6y +y= 128
1.6y= 128
Y= 128/1.6
Y= 80
X+y= 128
X+80= 128
X=128-80
X= 48

Step-by-step explanation:
you need to find the length of all the outside edges. for the triangles you will need to use the pythagorean theorem
Answer:
T = 530N + 250
Step-by-step explanation:
For the first plan, Heather will deposit $250 and then save $135 per month.
So, that is 250 + (135 x N) where N is the number of months she saves the $135.
So if it is for 3months,
We will have:
t¹ = 135N + 250
= 250 + (135 x 3)
= 250 + 405
= $655
For the second plan, there is no initial deposit, but she will save $395 per month.
That is 395 x N
t² = 395N
For 3months, we have 395 x 3 = $1185
Therefore the total for both plans in 3months = 655 + 1185 = $1840
Equation relating T to N
T = t¹ + t²
T = (135N + 250) + 395N
T = 135N + 250 + 395N
T = 530N + 250
Answer:
y = -3x-2
Step-by-step explanation:
the slope can be found using rise/run which comes out to be -3/1 and you can drop the 1 from the fraction to have -3. and then the y-intercept is found from where the line crosses the y-axis
